Jänschwalde: What we know about the explosion at the Brandenburg substation

A powerful explosion rocked the Turnow-Preilack substation near the coal-fired power plant Jänschwalde in Brandenburg on Tuesday morning, September 1, 2026. According to local police, multiple explosives were discovered at the site, with the exact number still under investigation but believed to be in double digits. The incident has raised concerns among authorities, with Brandenburg’s Interior Minister Jan Redmann describing it as an attempted sabotage. Despite the severity of the explosions, there has been no threat to public safety, and the overall electricity supply remained unaffected. The substation, located between Preilack and the village of Tauer, is part of the high-voltage transmission network that connects to the nearby Jänschwalde power plant. Redmann stated that the perpetrators aimed to introduce conductive material into the high-voltage lines using a “driving charge,” thereby causing short circuits. He noted that this method succeeded twice, resulting in a severe electrical discharge that caused noticeable disturbances in the ground. A staff member of the grid operator 50Hertz observed a fireball at the scene, though Redmann did not confirm detonations, instead referring to the event as a short circuit that affected the earth. The area around the substation includes a building constructed in the 1980s, which is still used by the operator. Additional structures, likely used for temporary housing during construction, remain empty. These facilities highlight the historical significance of the location, as the Jänschwalde power plant was built between 1976 and 1989 as the last new power station of the former East Germany. It continues to generate electricity, which is initially transformed at the substation before being distributed to regional and national consumers. Following the explosions, a brief interruption in the power supply occurred due to a flashover event, according to information from Die Zeit. However, the general electricity supply was not disrupted. At approximately 7:33 a.m., the second block of the power plant automatically shut down as a precautionary measure, confirmed by the operator. This automatic response underscores the safety protocols in place at such critical infrastructure sites. Authorities have begun their investigations, focusing on the nature of the explosives and the intent behind the attack. While the police have not yet identified specific suspects, they are examining whether the incident constitutes a criminal act. Redmann emphasized that the sabotage attempt could have had more serious consequences, given the potential for damage to the high-voltage lines. He described the event as a “heavy blow” to the energy infrastructure, highlighting the vulnerability of such systems to targeted attacks. The incident has sparked discussions about the security of energy infrastructure in Germany, particularly in light of increasing concerns over threats to critical facilities. Local residents expressed alarm but reassurance that immediate dangers had been mitigated. As the investigation progresses, officials will determine the extent of the damage and assess the need for additional protective measures. For now, the focus remains on ensuring the continued safe operation of the power grid and preventing future incidents.
